I don't think it is, but I wanted to make sure. If it isn't that is REAL dumb. My ATT contract runs out in June and I would get a 25% discount on Verizon through work. Switching to Verizon now will stick me with a non-4G phone for two years... bah. I would want to switch while Verizon is offering the unlimited data plan... not sure how long they will offer that.
